  • Prevent backslash from being parsed by javascript for a string

    - by user286269
    A Flash AS3 IRC application sends me a string like "f\reak" to my javascript. Irc allows the \ in usernames which poses a problem when its passed to javascript. "f\reak" become "feak" in javascript making the \r into a carriage return. Is there a way to read the absolute value of the string instead of parsing a carriage return? These don't methods didn't work str.valueOf() str.toString() str.charAt(position of the \ ) this just sees the carriage return as well and not a backslash

  • Create a UIView Subclass that calls a delegate function whenever it's parent viewController appears?

    - by Andrew Johnson
    UIViewControllers have viewWillAppear, viewDidDisappear, etc. delegate methods. I would like to create a UIView subclass that can be added to a viewController's view, and when that UIViewController apears or disappears, a delegate function is called. I could easily do this by putting function calls in the UIViewController viewWillAppear/viewWillDisappear delegate functions, but how can I encapsulate this behavior in the UIView?

  • Why LINQ will work this way?

    - by Benny
    public static ArrayList GetStudentAsArrayList() { ArrayList students = new ArrayList { new Student() { RollNumber = 1,Name ="Alex " , Section = 1 ,HostelNumber=1 }, new Student() { RollNumber = 2,Name ="Jonty " , Section = 2 ,HostelNumber=2 }, }; return students; } this doesn't compile: ArrayList is not IEnumerable ArrayList lstStudents = GetStudentAsArrayList(); var res = from r in lstStudents select r; but this will compile: ArrayList lstStudents = GetStudentAsArrayList(); var res = from Student r in lstStudents select r; Can anybody explain? what's the magic here?

  • Start exe even with missing dependency dlls?

    - by k3b
    In Dotnet2.0 and later a program refuses to start if one of its dependent (static referenced) dlls are missing. With Dotnet1.1 and 1.0 the program started but crashed later when trying to use functionality of the missing assembly. I wonder if there is something like a compiler switch , configuration option or a dotnet [attribute] to allow me to start the app when certain dlls are missing. Is it possible without moidfying the sourcecode (execpt by applying some Attriutes)? I don't want to manualy load assemblies by programcode or use IOC-Framworks. Update: With "static referenced dlls" i mean the opposite of dynamicly loading a dll in my own programcode using reflection and Assembly.Loadxxxx(). Update 2010-12-25: This scenario happens for example if you want to use Log4net with Dotnet4 clientprofile together with a WinForms-Aplication: Log4net requires System.Web.dll that is not in Dotnet4-Clientprofile. You must install dotnet4-web-support to use the winforms-aplication that is compiled against log4net unless there is some magic Compiler-switch/Attribute/Configuration that i am still looking for.

    I have a MMC client that runs on a .Net system, that invokes web methods on a server running on a linux box. The first task the client needs to do is to perform user login. It prompts the user for username and password. What is the best way for the client to authenticate the user's credentials. The password cannot be sent as plain text. The web server implements a web method called ValidateUser().

  • Basic Java Multi-Threading Question

    - by Veered
    When an object is instantiated in Java, is it bound to the thread that instantiated in? Because when I anonymously implement an interface in one thread, and pass it to another thread to be run, all of its methods are run in the original thread. If they are bound to their creation thread, is there anyway to create an object that will run in whatever thread calls it?

  • Call plugin class in Java

    - by Josh Meredith
    How can I call a class in Java, when the name of the class won't be known at compile time (such as if it were a plugin). For example, from a GUI, a user selects a plugin (a Java class), the application then creates a new instance of the class, and calls one of its methods (the method name would be known at compile time (e.g. "moduleMain")). Thanks for any input.

  • VB.net 'cross-referencing' tables.

    - by Lee
    Hello, I have a DataGridView that is being filled with data from a table. Inside this table is a column called 'group' that has the ID of an individual group in another table. What I would like to do, is when the DataGridView is filled, instead of showing the ID contained in 'group', I'd like it to display the name of the group. Is there some type of VB.net 'magic' that can do this, or do I need to cross-reference the data myself? Here is a breakdown of what the 2 tables look like: table1 id group (this holds the value of column id in table 2) weight last_update table2 id description (this is what I would like to be displayed in the DGV.) take care, lee BTW - I am using Visual Studios Express.

Are they part of .net or they are just tell something to CLR ? or ?

  • Multi-part gzip file random access (in Java)

    - by toluju
    This may fall in the realm of "not really feasible" or "not really worth the effort" but here goes. I'm trying to randomly access records stored inside a multi-part gzip file. Specifically, the files I'm interested in are compressed Heretrix Arc files. (In case you aren't familiar with multi-part gzip files, the gzip spec allows multiple gzip streams to be concatenated in a single gzip file. They do not share any dictionary information, it is simple binary appending.) I'm thinking it should be possible to do this by seeking to a certain offset within the file, then scan for the gzip magic header bytes (i.e. 0x1f8b, as per the RFC), and attempt to read the gzip stream from the following bytes. The problem with this approach is that those same bytes can appear inside the actual data as well, so seeking for those bytes can lead to an invalid position to start reading a gzip stream from. Is there a better way to handle random access, given that the record offsets aren't known a priori?

  • Wrapping \NewEnviron into \newenvironment fails

    - by o_O Tync
    Hello! I am trying to wrap an environment created with \NewEnviron (package 'environ') into an old good \newenvironment: \NewEnviron{test}{aaa(\BODY)bbb} \newenvironment{wrapper}{\begin{test}}{\end{test}} \begin{wrapper} debug me \end{wrapper} However, this gives me a strange error: LaTeX Error: \begin{test} on input line 15 ended by \end{wrapper}. LaTeX Error: \begin{wrapper} on input line 15 ended by \end{document}. If I replace \NewEnviron{test}{aaa(\BODY)bbb} with \newenvironment{test}{aaa(}{)bbb} — everything works as expected! It seems like \NewEnviron fails to find its end for some reason. I'm trying to do some magic with 'floatfig' wrapped into a \colorbox so I need a way to convert \colorbox to an environment and wrap it into another one. I can define a new command but it's not a very good idea. Thanks in advance!

  • Testing Rails Metal With Cucumber/rSpec

    - by nkabbara
    Hi, I'm trying to stub a third party service that my metal talks to. It seems rspec mocks/stubs don't extend all the way to the Metal. When I call stubbed methods on objects, it calls the original one and not the stubbed one. Any idea of how I can have rSpec doubles extend all the way to the metal? Thanks. -Nash

  • Which SEO practises are likely to be responsible for SO questions appearing so quickly in Google sea

    - by morpheous
    Does anyone have some idea as to how come questions posted here on SO are showing up so quickly on Google?. Sometimes questions submitted are appearing as the first 10 entries or so - on the first page within 30 minutes of submitting a question. Pray tell, what sort of magic is being wielded here? Anybody have some ideas, suggestions?. My first thought is that they have info in their sitemap that tells google robots to trawl every N minutes or so - is that whats going on? BTW, I am aware that simply instructing Googlebots to scan your site every N minutes will not work if you dont have quality information (that is constantly being updated on your site). I'd just like to know if there is something else that SO may be doing right (apart from the marvelous content of course)

  • rails declarative authorization, permit all actions for controller?

    - by SooDesuNe
    using the delcarative_authorization gem for rails, is there a shortcut to allow a role access to all controller actions? privileges do # default privilege hierarchies to facilitate RESTful Rails apps privilege :manage, :includes => [:create, :read, :update, :delete] end isn't sufficient, because I have more controlling methods than just CRUD in my controllers. Something like: role :foo do has_permission_on :bar, :to =>[:all] end would be perfect, but I'm not finding it in the docs.
